WINDOW'SCHEEN.

To all wlto'm/ it Inn/,1; concern:

Be it known that l, CnAnLEsCAnLllinscn, a citizen of the United States, residing at Tri p, county of Hutchinson, State ofv South dura-ble." construction and Y,hereinad'ust- ,bleniel ersfwillbee'mployed whereby the `frame canb expanded or contracted previoils Itothe ap lication'of the netting to produce a compieted screen -ot lixed predeterminedlshape and dimensions, wherein said by an efficient, dura 'frame screen for wmdowsand the like will be members of the completed' screen will be rigidly held' and`locked a ainst adjustment.

further object of t e invention is to provide .an-improved metal frame for screens, foravindows, and the like capable of adjust- 'ment-to.various sizes before the avplication oli -the netting thereto and whic will be firmly locked in the desired adjustment to form a screen of tixefdpermanent dimensions by the act of' securing the netting to the frame;

A further object of the invention is to provide improved means for securing the netting to meta-l .frames for window-screens and the like. A".

A further object of the invention is to provide certain 'improvements in constructions and arrangements of arts and details wherele, and strong metalproduced.

The'nventionconsists in certain novel features in construction or in combinations and arrangements of parts,'as' more fully and particularl'y ,described hereinafter..

Referring to the accom anying drawings, which show fo'r purposes o explanation a construction, as an example 'among other embodiments'withinthe spirit and sco of my invention, Figure 1 is an elevation cih screen constructed in accordance with my invention, showing the outer side et the screen. Fig. 2 is a cross sectional view on the line 2y 2, .Fig 1. Figi 3 is a detail perspective Specification of Letters Patent,

view ol a corner-piece and portions of two side rails or members detached therefrom, the nettingsecuring flanges thereof being shown in position to receive the netting, a portion of the netting being shown with 'its edges bent to fit under s aid flanges. Fig. 4 is an elevation of a corner portionof the completed screen, showing the inner side or face thereof; Fig. 5 is a detail perspective of one end of the cross-brace, showing its osition before being secured in the frame. ig. 6 is section, onf'an enlarged scale, on the line 6 6,

"he screen-frame comprises sheet-metal` longitudinal telescoping or overlapping members or sections, which previous to the application' of the netting can slide longitudinally of each other to reduce a frame of the required shape and) dimensions to which the nettingis secured and which in the com leted screen is rendered rigid against expan mg or contracting adjustment.

Suitable devices are employed to 'connect and secure the side rails or members of the frame together and form the corners of the frame. For instance, in the construction illustrated as an example I show four similarly-formed frame-rails or side bars each com osed of two similar sections and four simi ar corner-pieces. Each corner-piece' is V-shaped or angular and is formed in one piece of metal, usually a strong solid casting, consisting of the flat plate or body ortion 1, one side face of which has the angu ar raised bead or rib 2, cxtendin longitudinally along or throughout the lengt i of the angular outer edge of the corner-piece. Each corner-piece is usually formed with a transverse erforation or bolt-hole 3 through the flat ody or plateportion about midway between the a ex of the angular bead 2 and the apex of t c angular inner edge oi the late portion.

The corner-pieces can be com osed of any 'suitable metal and,1f desired, can be treated rusting or corrosion.

IOO

for coated with suitable material toprevent Each side or rail-section is bont or struck Each sheet-metal rail-section is formed in one piece with the fiat longitudinal body portion 4 at its outer longitudinal portion bent outwardly to form the hollow roll or bead 5 o ver lthe outer side face ofthe iiat body portion 4 Iglo and extending lon itudinally throughout the lengthl thereo. e roll 5 is not completely closed; but its longitudinal tree edge 6 is usually turned or bent inwardly'and radially of the roll and awa from the outer face of the body portion 4 o the section, thereby leaving the narrow slot or opening longitudinally along the inner portion of the roll and -be each nietal sheet forming length of the section.

tween the same and the surface of said body portidn, j 'f1 r The inner-or opposite longitudinal edge of a rail-sectionis bent back to form a netting-securing flange 7, .extending longitudinally throughout the The roll 5 is arranged along the outer side face of the rail-section, while the flange 7 isairanged-along the opposite or inner side fai-,e of the section, and when the section leaves thel forming-machine said flange 7 is not closed down against said face, but is spaced therefrom, say, about one-half an inch and forms an acute angle therewith, as shown by Fig. 3.

The four rails or side members of the frame are preferabl similar in construction; but the. ho'lizonta rails may differ in length from the vertieal rails, although not necessarily, as #be difference between the width and height of the frame can be rovided for by adjusting the seetions lon 'tu inally,evenii" all the railseetions are oft esame length. `W here each rail is composed of two sections, suoli as pre-Y viously described, the outer ends of the two sections are forced ontothe ends of two eorner-pieces7 and the inner ends of the seetions are slipped longitudinally together or tele,- scoped to sueli an extent as recluired to produee a ruil ofthe required leng 'lhe meetingends of the rails are forced onto the, opposite ends of the corner-pieces, so that the flat body )ortions of the rails overlap the flat inner si( e far-.es of' the eorner pieces and so that said flat portions of eaeh pair of meeting ends overlap eiieh other. The meeting ends can `then be secured together and to the eoriier-'pieees by bolts S, passed transversely' through said overlapping ends of the rails and through the bolt-holes in the.-

eorner-pieees. 'lhe rail ends slip longitudinally onto the eorner-pieees. with the hollow rollsof t'lie rails einbraeing the beads of'- the (fumier-meras, so that the eorner-pieees are what expander arranged at the outer side. fures o' the rails. 'l`he elastieity of the metal of' the rails eauses the rolls to tightly fit land grip 'tlie eorne'rpieees und maintain the positions of they rails on the eoriierier-es, as the rolls nre somel whenf'oreed on lhe. eorneriieees,

'llle inturiied edge o lip enii be. removed from the outer end nortioJis of eaeh vertieul and horizontal ruil to perni'it the railuolls to slide. on and einhraee the heads or outer edge portions of. the eorner-pieees. 'llie meeting ends of thi etioiis of euch rail aro slipped longitudinally together to telescope or ov rlap the distance required to form the railebf the desired length. The roll of one section is forced open 'or expanded by inserting the' roll of the other section thereinto, so that the flat body portions of the rail-seetions longitudinally overlap with the netting-securing flanges overlapping, one resting longitudinally within the other and the rolls of the two sections telescoped; A Considerable force is required to thus telescope the two sections by reason of' the stiff' ness of the sheet metal, and hence the two interlocked teleseoped sections are held in the position to which they have been adjusted by friction and by the gri ping clamping action of the expanded'roll. .ach rail-section is adjusted to the desired length by driving or forcing the sections to telescope or over` lap therequired distance. Previous to the a lioation of the netting to the frame and t e ocking of the rail-sections together said sections are slidableon each other to permit adjustment of the frame to the desired size and dimensions with the various nett1ng-seeuring flanges at the inner side face of thefranieand forming a practically continuous flange around the opening of the screen-frame and along the four inner edges of saidframe,.while the various rollsand beads of the rail-sections and Aoorii'er-pieees are preferably located at the outer side face ol' the frame, forming a practically continuous roll completely around the frame and along the four outer edg'es thereof.

1f desired, I can employ an intermediate or cross baroi'hraee between two opposite rails-- for insta-nee., between the two vertical rails and attache-d thereto about at the joint between the two sections of each rail. For instance, l show a.bar l0, eoniposed of two overlapping or teleseoped sections, eaeli seetion being formed of n pieeeol' longitudinallydonbled'stifl` sheet metal at its outer end doubled back upon itself at l i, with its fitec end bent outwardly to forni an angulurly arranged or inclined flange. l2, forming a V- shaped notch or socket in connection with the-.doubled portion li.' This notch is so formed as to fit onto the inner edge of the rail, with thedouble portion 1 l resting against. the outer side. faee of the flut body portion of the rail and'with the end or flange l2 resting against theonter faee of the netting-securing flange of the rail. 'llie inner ends of' the two ser-.tions ol' the eross-bar loiigitudiiiall overlap or telescope, so that the bar van ie. oontraeted to the desired length, the metal foriniiig the seetions of the 'bar being sullieiently still to rigidly hold the sei-tions together al ter adjustment.

lf will he observed that the eross-har extends hetweeii the inner edges of the opposite. rails and that the V-shaped notehes oi' soekels at the ends of the bar lit t he inner edges of the rails, .thereby bran-.ing the rails and hold-l TOO ing them properly spaced and also forming a i support across the netting. However, I Wish it und .stood that I do not desirete limit all features of my invention to employment in connection with a cross-barL Thecross-bar is applied to the frame, having been previously adjusted to the required `length before the netting is lapplied to the frame, and the frame is also adjusted to the relagiired dimensions before the netting is a p- 1e p The sheet of wire-netting 13 is cut of a size to cover the opening ofthe screen-'frame and extend over the netting-securing flanges 7- and beyond the same.` This sheet of netting is then placed against the inner side face of the screen-frame and resting on the flanges 7 The edges of the netting which project bel0nd said flanges are then bent down and inwardly' to hookv or extend beneath said flanges. After the edges of the netting have thus been bent under theflanges4 said flanges by any suitable means or method are closed or bent down tightly to the inner side faces of therails, thereby forming seams tightly ceinpressing and gripping the edges of the netting etween the flanges and faces of the rails, wi th the netting facing the outer faces of the flanges.

The V-shaped end sockets of the cross-bur are also closed by the act of compressing the netting-securing flanges, thereby firmly securin the cross-bar to the rails, with the netfging tightly stretched against andacross said Practicallyl every wire of the netting is gripped and vsecured by the netting-securinganges, and the netting is tightened and drawn taut by the act of closing down the flanges to forni the netting-securing seam. The seam thus formed also rigidly locks the frame-sections together by reason of the longitudinally-overlapping portions and flanges of the dierent sections of the frame, thereby cooperating with the telescoped rolls of' the frame-sections in forming avery rigid, stron g, and durable metal frame for screens and the like.

The corner-pieces might be formed otherwise than by solid castings, and adjustment. might be provided for at the corners of the frame by causing the corner-pieces and rails to telescope to a greater or lesser extent, and adjustment of each rail might be provided for otherwise than by employing two sections. a
